10.5 hrStep-by-step explanation:
7 hr/3 pumps
So first we want to find the unit rate which would be...
5.25 hr/1 pump
Now that we found the unit rate we are going to multiply it by 2 because there are 2 pumps...
5.25*2=10.5
So our answer is 10.5 hr/ 2 pumps

Sam cut a 28-foot rope into 4 equal pieces. How long is each piece of rope in inches? -HELP PLEASE THIS IT DUE IN 5 MINUTESSS
Answer:
84 inches
Step-by-step explanation:
12 inches are in 1 foot, so you take the number of feet (28) and multiply by the number of inches in a foot (12)
28×12=336 (inches)
then you take 336 and divide by 4 to get your 4 equal pieces.
336 divided by 4 = 84, 84 inches

A rental car company charges $38.38 per day to rent a car and $0.14 for every mile driven. Camden wants to rent a car, knowing that: He plans to drive 350 miles. He has at most $270 to spend. Which inequality can be used to determine xx, the maximum number of days Camden can afford to rent for while staying within his budget?
Answer:
5.75 days
Step-by-step explanation:
Given data
let the number of days be x and the number and the number of miles be y
so that the cost of the rental will be
c= 38.38x+ 0.14y---------1
we are told that the amount at hand is $270
hence
270=38.38x+ 0.14*(350)
solve for x
270= 38.38x+49
270-49= 38.38x
221= 38.38x
divide both sides by 38.38
x= 221/38.38
x= 5.75 days
Hence the number of days is 5.75 days
What is the measure of the vertex angle
Answer:
Vertex angle = 124°
Step-by-step explanation:
m<BAC = m<BCA (base angles of isosceles ∆ are congruent)
7x + 1 = 5x + 9
Collect like terms
7x - 5x = -1 + 9
2x = 8
divide both sides by 2
x = 4
Vertex angle = 180 - ((7x + 1) + (5x + 9)) (sum of triangle)
Plug in the value of x
Vertex angle = 180 - ((7*4 + 1) + (5*4 + 9))
Vertex angle = 180 - (29 + 29)
Vertex angle = 124°
¿Cuáles son las longitudes de un terreno rectangular, si se sabe que el ancho es dos veces más pequeño que el largo, y que su área es de 16, 200 m2? cuanto mide el ancho cuanto mide el largo
Answer:
El largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m
Step-by-step explanation:
Un rectángulo es un cuadrilátero con dos lados de igual longitud y dos lados de igual ancho que contiene cuatro ángulos rectos. Para encontrar el área de un rectángulo, debes multiplicar su longitud por su ancho. Es decir, el área del rectángulo es igual al largo por el ancho.
En este caso, sabes que el ancho es dos veces más pequeño que el largo. Entonces, siendo el largo x, el ancho tendrá un valor de x÷2.
Siendo el área del terreno rectangular 16,200 m², entonces
x*(x÷2)= 16,200 m²
Resolviendo:
x² ÷2= 16,200 m²
x²= 16,200*2 m²
x²= 32,400 m²
x= √32.400 m²
x= 180 m
Entonces, el largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m (180 m÷ 2)

Choose the solution to this inequality. 43< − 8/3 y
Since there is a negative on the y term, we need to get rid of that and thus flip the sign at the same time. Getting.
-43>8/3y
Now we just need to divide 8/3 on both sides dividing 8/3 on left can also be written as *3/8
-43*3/8>y
Now flip this entire equation
y<-43*3/8
y<-129/8

its a right triangle 20ft and 24ft?
Answer:
a triangle, I'm guessing 20ft and 24 ft on the outsides,
would be:
Equation to get the area of a triangle: (A*B)/2
(20*24)/2=Area
20*24= 480
480/2= 240
area= 240
Answer: 240 ft²
Step-by-step explanation:
1. Multiply the base and the height.
2. Divide the product you get by 2.
=> 20 * 24 = 480
=> 480 / 2 = 240
Barney was driving at 25 mph. A car pulls out 30 ft ahead of him. The coefficient of friction, f, is 0.7. Which statement is true? A Barney hits the car. B Barney stops less than a foot from the car. C Barney misses the car by 3 ft. D Barney's skid marks measure 23 ft.
Answer:
B Barney stops less than a foot from the car.
Step-by-step explanation:
From the information given:
The initial speed of barney [tex]v_o[/tex] = 25 mph
Coefficient of friction [tex]\mu[/tex] = 0.7
Recall that
1 mph = 0.447 m/s
Then
[tex]v_o[/tex] = 25 × 0.447 m/s
[tex]v_o[/tex] = 11.175 m/s
The force of friction acting on the barney is expressed as:
[tex]F = \mu N \\ \\ F = \mu mg[/tex]
[tex]ma = \mu mg[/tex]
[tex]a = \mu g[/tex]
a = 0.7 × 9.8 m/s
a = 6.86 m/s²
Since the force acts in an opposite direction to the motion of Barney, Thus the acceleration must also be negative.
a = -6.86 m/s²
Now;
Suppose Barney stops after traveling a distance (s), so that the final speed is zero.
Then;
Using the kinematic equation;
[tex]v^2 - v_o^2 = 2as[/tex]
[tex]0 - (11.17)^2 = 2 \times (-6.86) s[/tex]
[tex]-124.76 = -13.72 s[/tex]
[tex]s = \dfrac{124.76}{13.72}[/tex]
s = 9.09 m
Recall that;
1 m = 3.28 ft
So;
s = 9.09 m = 9.09 × 3.28 ft
s = 29.81 ft
∴
The distance traveled by the Barney is 29.81 ft which implies that Barney stops less than a foot from the car.

Answer:
ML = 7.5
Step-by-step explanation:
The parallel lines divide the transversals proportionally.

Answer:
8Step-by-step explanation:
Given the expression 3 * 2 2/3
This can also be expressed as;
3 * 2 2/3
= 3 * 8/3
= (24/3)
= 8
hence the product of both numbers is 8
The equivalent value of the fraction is A = 8
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first fraction be represented as p
Let the second number be represented as q
Now , A = pq
when the value of p = 2 2/3
And , when the value of q = 3
On simplifying the equation , we get
A = ( 2 2/3 ) / ( 3 )
So , the left hand side of the equation is equated to the right hand side by the value of ( 2 2/3 ) / ( 3 )
A = ( 2 2/3 ) / ( 3 )
A = ( 8/3 ) / ( 3 )
On simplifying , we get
Multiply by 3 on the fraction , we get
A = ( 8 x 3 ) / 3
A = 8
Therefore , the value of A = 8
Hence , the fraction is A = 8
